"Vitamin D, when consumed at very high levels, can lead to serious health issues in dogs including renal dysfunction," the statement read.

The affected food supplies could create a range of health issues for dogs.

"Pet parents with dogs who have consumed any of the products listed and are exhibiting any of these signs should contact their veterinarian. In most cases, complete recovery is expected after discontinuation of feeding."

In a letter to veterinarians, the company's US Vice President and General Manager, Jesper Nordengaard, said it was with "sincere regret" that he was writing to announce the recall expansion.

"Following the recall, we conducted a detailed review of our canned dog foods. As we had expected, that review confirmed that the issue is isolated to the same vitamin premix used in canned dog foods and limited to specific production lots," he wrote.

"However, our review did determine that there were additional products affected by that vitamin premix, and it is for that reason that we are expanding the recall," the letter read.

Many of Hill's popular Science Diet and Prescription Diet canned foods have been included in the second recall.

Pet owners have been told that none of the company's dry foods, cat foods or treats are affected by the second recall.

Those who bought the recalled products are advised to discontinue feeding them to their pets and dispose of them immediately.

Pet owners can also have discarded products replaced at no cost, by contacting their pet store, veterinary clinic or online retailer where they bought it.
